Flat ground jump and spin

I know there have been threads on this before, how big of a rotation can you do on flat jumping up?  Well anyway I was stumbling through videos and came across this Soviet "breakdance" video.
Fast forward to 1:38 and watch the guy jump and spin, any idea how big he is spinning each jump?  Looks like 720 to me, that's crazy on it's own, but the fact he does it 14 or 15 times.... crazy.  Someone should try to repeat this and make a video of the failure that will commence. 

There is also some other crazy shit like spinning on their knees and the bent down foot kicking... things.
